T o all {wlwm it may concern.'

Be it known that l, Vieron li. PALM, a citizen of the United States ofAmerica, residing at Butler, in the county of Butler and State of?ennsylvania, have invented certain newand useful improvements inUil-Well i)evices, of which the following is a speciiication, referencebeing conipanying drawing.

This invention relates to improvements in oil well devices,- and theinvention has .for its primary object to dispense with .the ordinarysucker rods employed for operating a working barrel valve, and toprovide novel means whereby the cableor continuous connection can beused for operating a working barrel valve. To' this end, iba-ve deviseda novel stuiiing box adapted to be located above the working barrel oian oil weil, the

had therein tothe acstuiling box being constructed whereby itl can beeasily removed from a working barrel at4 any desired time or located inthe well whereby it cannot be accidentally displaced.

The detail construction entering into my invention will be presentlydescribed and then specifically pointed out in the appended claims.

in the drawings, Figure i is an elevation oi my improved device., Fig. 2is a vertical sectional view ol' the saine, Fig. 3 is a horizontalsectional view taken on the line :r-sc oi" Fig.

V2, Fig. 4 is a similar view taken on the line -y-y of Fig. 2, Fig. 5 isa perspective view of one of the locking members, Fig. 6 is u verticaisectional View of a buiier or block used in connection with the device,Fig. 7 is a plan of the stand pipe of the device, and ii ig. s is a pianof a clamp used in connection with the stand pipe.

In the accompanying drawings, 1. designates the tubing or" a well inwhich is located e working barrel 2 having a lower standing valve 3 anda working barrei valve 4. Connecting with the upper end of the workingbarrel 2 is a cylindricalcasinc 5, retained within the tubing 1 of theweii by resilient arms 6 having their ends loosely mounted in coils 7carried by the casing 5. The upper end of the casing 5 is threaded, asat 8 and provided with a taperin r seat 9.

Screwed upon the end of the casing 5 is an eXteriorly threaded housing10 having circumferentially arrangedv segment shaped grooves 11 formedtherein, these rooves receiving the depending pins 12 oi segmentshapedblocks 14, said blocks preventing a full rotation of the pipe 17 ineither direction.

Screwed upon the housinup 1() is an exteriorly threaded cup 15 for hoding the ilangcd end 16 of a stand pipe 17, said stand pipe hsving itslower end cut away, as at' 17, to clear the blocks 14 which extendinwardly and lock the lower tapering end 20 of a pipe 19 in the taperingscat of the casing 5. A gland 18 is threaded upon thelcup'l for holdingpacking (not shown) in' engagement with the stand ipe 17. The pipe 1.9is connected by a b ook 20*1 with another section oi'pipe 2i, said block20 having a rectangular opening 22 formed therein for aplunger 23, whichis substantially rectangular in cross section, whereby said plungercannot rotate in the block- 205. The upper end oi the plunger 23 isconnected to a cable 24, which can be provided with a plurality ofblocks 25a to prevent said cable from being cut or injured by the pipe2l- The lower end ofthe plunger 23 carries a socket 25, by virtue ofwhich said plungcriis connected to thc working barrel Avalve 4.

interposed between the lower cnd of the pipe 19 and the socket 25 is acoil spring 26, said spring being employed for retaining the Workingbarrel vulve 4 in aiowercd position.

The cable 24 is :ula )ted to be connected lo an ordinary walking lployed for vertically reciprocating the working barrel valve/4 to raiseoil in the casing 5 and the pipes 2() und i7, the oil passing throughopenings or pcrforations 27 formed in the pipe 1Q.

in operation, the spring 26 is adapted to lower the working barrel valve4, while the Walking beam of an oil well device is adapted to raise theworking barrel valve through the medium of the cable 2li. The casing 5will be normally held within the tubing 1 of the working barrel by theresiiientarni 6, these arms, however, permitting of the working barreland casing being removed by eileicnt pulling power from above the well.it will of course be understood that the stand pipe 17 extends to thetop of the well, and to prevent said stand pipe from accidentallyrotating, I use a clamp 30 which is secured to the upper end of thestand pipe, also ltoan object adjacent to the stand pipe, whereby saidpipe and clamp cannot rotate. it is desired to remove the pipe 19, it isonly necessary to partially rotate the plpe 17 and When l by virtue ofthe cut away end of said pipe move the blocks 14. The segment-shapedgrooves l1 of the housing 10 move the blocks .I4 outwardly releasing thetapering shouldered end of the perforated pipe 19.

lt will be observed from the foregoing description, that I have devisednovel means whereby an ordinary wire cable can be used for operating theworking barrel valve of a working barrel, thus dispensing with theordinary sucker rods, commonly used for this purpose.

Having fully described my invention, what claim and desire to secure byLetters Patent, is-

1. The combination with the tubing of an oil well, the working barrelthereof, and the working barrel valve, of a casing connecting with saidworking barrel and fixed within said tubing, a stuffing box carried bythe upper end of said casing, a perforated pipe mounted in the upper endof said casing, a stand ipe surrounding said perforated pipe and heil'lby said stuffing box, a block carried by said pipe, a rectangularplunger movabl mounted in said block and connecting with said workingbarrell valve, a spring interposed between said perforated pipe and saidworking barrel valve, a cable connecting with the upper end of saidplunger and blocks carried by said cable, substantially as described.

The combination with the tubing of an oil well, the working barrelthereof, and the working barrel valve, of a casing connecting with saidworking barrel and fixed within said tubing, a stuffing box carried bythe upper end of said casing, .a perforated pipe mounted in the up erend of said casing, a stand pipe surroun ing said lperforated pipe andheld by said stuffing box, a block carried by said pipe, a rectan ularplunger movabl mounted in said bloc and connectingwith said barrelvalve, a spring interposed between said perforated ipe and said workingbarrel valve, and a cablb connecting with the upper end of said plunger,substantially as described.

3. In an oil device, the combination with a working barrel and avalvethereof, of a casing carried by the upper end of said working barrel, astand pipe extending upwardly from said casing, a stuffing box forholding said stand pipe upon said casing, a perforated pipe arranged inthe upper end of said casing and surrounded by said stand pipe, a

plunger operating in said perforated pipe and connecting with saidvalve, a spring interposed between said perforated ipe and said valve, acable connecting with t e upper end of said plunger, means forpreventing said plunger from rotating, and means for preventing saidstand pipe from becoming disengaged from said casing, due to rotation.

4. In an oil well device, the combination with a working barrel and avalve thereof,

of a casing carried by said working barrel, a

with a working barrel and a valve thereof,

of a casing connecting with said barrel, a stand pipe connecting withthe upper end of said casing, a perforated pipe located within saidstand ipe, a plunger slidably mounted in said pe orated pi e andconnecting with said valve, and a cablle connected tothe upper end ofsaid plunger.

6. ln an oil well device, the combination with the working barrel, andthe valve thereof, of a casing connectin withsaid barrel, a dperforatedpi e detac ably mounted in sai casing, a punger o erating within saidpipe and connecting wit said valve and means to lock said perforatedpipe in said said casing.V

In testimony. whereof I affix my signature in the presence of twowitnesses.
